Laura Dreyfuss, Olivia Puckett and Ben Ross, of the six-time Tony Award winning musical, performed songs like “Shake It Off” by Taylor Swift and “Let it Go” from Disney’s Frozen to four young patients at Hassenfeld Children’s Hospital at NYU Langone.

They also performed a rendition of “How Far I’ll Go” from Disney’s Moana before inviting their young fans to join them in a dance party.

“It made her smile,” said Freddy Rojas, father to 4-year-old Luciana. “She hadn’t danced since the surgery.”

He told InsideEdition.com Luciana was born with a tethered spinal cord and had her first surgery at 4 months old.

She was readmitted to the hospital earlier this month to have further treatment related to her spinal cord, and the day the Broadway stars came to visit was the day she was discharged.

“It helped give her a nice send off,” her dad said. “She enjoyed the dancing the most.”

Among the VIP guests of the musical stars was a young girl with a perforated appendix, a patient with epilepsy and a child with a brain tumor.

“These cast members were so enthusiastic and relatable,” said Christina Brown, who organized the event for the hospital. “When we have something special like a Tony Award-winning Broadway cast, it elevates the excitement and it makes the day different than any other day.”

Brown told InsideEdition.com they regularly use music therapy to help kids through difficult hospital stays.

“It’s scary and painful and it turns their normal world upside-down,” she explained. “Music does have the power and ability to help kids express themselves. These kinds of events lift their spirits.”
